Title: A storage heater
IPC: H01H37/34
Filed: 1967-09-29
Abstract: 1,203,614. Storage heaters. G. BAUKNECHT G.m.b.H. ELEKTROTECHNISCHE FABRIKEN. 29 Sept., 1967 [1 Oct., 1966], No. 44408/67. Heading F4U. In a storage heater having a charging regulator or a device for indicating the heat content of the core, the temperature senser of the regulator or device is located outside the core and heat is transmitted from the core to the senser via a metallic heat conducting bridge. As shown, the metal bridge 7 comprises a portion 7b, which is disposed within the insulation 5 surrounding the core 2 and is spaced from the core by a block of insulation 4, and a portion 7a which projects from insulation 5 and radiates heat to the bimetallic senser of a charge regulating switch 6 in series with the core heating element 3. The bridge may additionally be heated by an auxiliary electric resistance element which in one embodiment (Fig. 2, not shown) is connected in series with a temperature dependent resistance located in the insulation block 4 so that as the temperature of the core rises the heat output of the auxiliary element increases, and in another embodiment (Fig. 3, not shown) is controlled manually or in response to outdoor temperature. A manually regulable potentiometer is provided in series with the auxiliary element in both embodiments. In further embodiments (Figs. 6 and 7, not shown) portion 76 of the bridge is in direct contact with the core, either over the whole face area of the portion (Fig. 6) or at spaced locations thereon (Fig. 7). In the former case, portion 7a of the bridge includes a section of reduced cross-sectional area to reduce the degree of heat transmission and in both embodiments heat is transferred from portion 7a to a casing surrounding the core insulation via a block of thermal insulation. The latter may be associated with a heating element controlled in accordance with outside temperature.

Abstract: 1,186,667. Colour television. SYLVANIA ELECTRIC PRODUCTS Inc. 30 Sept., 1968 [28 Sept., 1967], No. 46388/68. Heading H4F. A colour video tape recorder and colour television receiver system comprises a colour television receiver 13, Fig. 1, having an RF tuner connected to input 21, demodulator circuitry connected to input 49, a video detector connected to output 27, and a subcarrier reference oscillator connected to output 39, and a colour video tape recorder 11 having a record/ play unit connected to input 37, a subcarrier oscillator connected to output 51 and arranged to receive an input from the record/play unit, and modulator means connected to output 23 and arranged to receive inputs from the record/ play unit and from an RF oscillator in the recorder. A two-pole switching means 19 is connected to the input 21 of the receiver which during the record cycle of operation is connected to receiving antenna 17 (the receiver monitoring the received signal to be recorded), and during the play cycle of operation is connected to the video signal output 23 of recorder via matching network 25. An adapter network 15 connects the video detected output 27 of the receiver to the record/play unit input 37 of the recorder and provides impedance matching therebetween, and connects the subcarrier output 39 of the receiver to the demodulator input 49 of the receiver during the record cycle of operation and connects the subcarrier output 51 of the recorder to the demodulator input 49 of the receiver during the play cycle of operation. The subcarrier burst signals from the record/ play unit activate the subcarrier oscillator of the video tape recorder to thereby provide a continuous wave subcarrier signal output at terminal 51 which is in synchronism with the recorded colour burst signals and closely follows any speed variations which may occur in the video tape recorder. An amplifier, a tint control network and a relay are connected between input 55 and output 45 of the adapter, the relay coupling the output of the amplifier to the output 45 during the presence of a subcarrier signal at input 55, i.e. when energized, and coupling the subcarrier signal at input 43 to output 45 when de-energized. A tint control is required because the control in the subcarrier oscillator of the receiver does not affect the phasing of the subcarrier signal from the video tape recorder.

Title: Improved apparatus for spectral analyses
IPC: G01J3/42
Filed: 1965-11-11
Abstract: 1,133,203. Photo-electric spectral absorption analysis. OPTICAL COATING LABORATORY Inc. Nov.11, 1965 [Nov. 24, 1964], No.47865/65 Heading G1A. In a photo-electric spectral absorption investigation a sample beam and a reference beam are passed through a circular filter which is rotated to selected successive wavelength bands from the two beams. A photo-electric device receives the two beams alternately and drives a shutter in the reference beam to balance the two beams. The degree of shutter movement indicates the amount of absorption of a sample in the sample beam and provides a Y-signal to a moving chart recorder, the X-movement of the chart being correlated with the movement of the circular filter selecting the wavelengths. In the figure radiation from a source 11, such as a hermit lamp, black-body or tungsten filament lamp is split into two beams S and R by the twin apertured plate 14 and passed alternately by rotating chopper disc 16 through windows 26 and 27, the reference beam window 27 having a variable shutter 31. A sample cell is placed in the sample beam S either as shown at 61 or as shown dotted at 62. The two beams after passing through the rotating circular filter 38 impinge upon a photo-resistor 48 whose output feeds one winding of a two phase motor driving the shutter 31. The other phase winding is fed from the power supply driving the chopper disc 16. The shutter 31 is thereby driven so as to balance the intensity of the sample and reference beams upon the photo-resistor and the movement is communicated to the pen of the chart recorder 56 as the amount of absorption by the sample. The chart speed is correlated with the speed of rotation of the circular filter, which is of the kind disclosed in Specification 1,117, 772.

Abstract: 1421871 Control of A.C. and D.C. motors LINSER-TEXTILMASCHINEN G.m.b.H. 22 Oct 1973 [21 Oct 1972] 49020/73 Heading H2J In a stretch twisting machine of conventional construction, the synchronous motors 22, 24 driving the thread feed roller 20 and the flanged rollers 23 are controlled by a supply unit 10 comprising an alternator 16 feeding the motors and being driven by a variable speed D.C. motor 15 which is coupled to an asynchronous motor 11 through a step-down gear train 12 and an overrunning clutch 13, the arrangement being such that the motor 11 is energised to drive the alternator 16 up to a predetermined idling speed via members 12, 13, 15, switch 30 is then closed to simultaneously energise the motors 22, 24, the resultant increase in load on the alternator 16 being absorbed without hunting by virtue of the chosen size of the motor 11, and finally the motors 22, 24 are run up to operating speed by control of the D.C. motor 15, which takes over the drive of the alternator 16 from the motor 11 allowing the latter to be switched off. The motor 15 may be manually or automatically controlled through a thyristor controller 19 responsive to a tachogenerator 17 coupled to the alternator 16 and may be switched on when it is desired to run motors 22, 24 up to operating speed or when the motor 11  is switched on, in which case controller 19 is preset to produce a speed lower than that of the motor 11. The latter may be of the polechanging type to produce a number of different idling speeds. The unit 10 ensures that the motors 22, 24 are run up to speed and subsequently operated in phase, which condition is also obtained during stopping by opening a switch 31 to de-energise the motor 15 and closing a switch 40<SP>1</SP> to dissipate the energy of the motor through resistances 41, the motors 22, 24 thereby driving motor 15 as a generator through the alternator 16 acting as a motor. The synchronous motors 33 driving the bobbins 32 of the stretch twisting machine are supplied from an alternator 37 driven only by a D.C. motor 36 having a controller 40, the operating conditions of the motors 33 being less critical than for the motors 22, 24. If desired, the D.C. motor 15 may be switched on to assist the motor 11 whilst it is driving the alternator.
